New Coleoptera records from New Brunswick, Canada: Mordellidae and Ripiphoridae.

Eleven species of Mordellidae are newly recorded for New Brunswick, Canada. Six of these, Falsomordellistena discolor (Melsheimer), Falsomordellistena pubescens (Fabricius), Mordellistena ornata (Melsheimer), Mordellaria undulata (Melsheimer), Tomoxia inclusa LeConte, and Yakuhananomia bidentata (Say)are new for the Maritime provinces. Falsomordellistena pubescens is new to Canada. Pelecotoma flavipes Melsheimer (family Ripiphoridae) is reported for the first time for New Brunswick and the Maritime provinces. Collection and habitat data are presented for all these species.

Introduction

This paper treats new Coleoptera records from New Brunswick, Canada, of the families Mordellidae and Ripiphoridae. A general overview of the Mordellidae (tumbling flower beetles) was provided by Jackman and Lu (2002). Adults feed on pollen and are often found on flowers of umbelliferous (Apiaceae) and composite (Asteraceae) species. Larvae feed mainly in living herbaceous stems, decaying wood, and fungi, depending on the species (Jackman and Lu 2002). Ford and Jackman (1996) summarized the known larval host plants of North American species of this family. The North American species were PageBreakrevised by Liljeblad (1945), and Bright (1986) provided a catalog of North American species. Later, Jackman (1991) made additions and corrections to the catalog, and Jackman and Lu (2001) and Lisberg (2003) made additional taxonomic changes to North American species. McNamara (1991) reported 14 mordellid species and subspecies for New Brunswick. Majka and Jackman (2006), in a review of the Mordellidae of the Maritime provinces (New Brunswick, Nova Scotia, Prince Edward Island), reported another six species for New Brunswick and removed Csiki, bringing the total number of known species to 19. Here, we add 11 species to the faunal list of the province.

Falin (2002) provided a general review of the Ripiphoridae (the ripiphorid beetles) of North America, including an overview of the biology and life history of various members of this family. Members of this family are unusual among Coleoptera in that they are endoparasitoids on insects such as aculeate Hymenoptera, Coleoptera (Anobiidae, Cerambycidae), and Orthoptera (Blattidae) (Falin 2002). Species occurring in the Maritime provinces are parasitoids of insects such as aculeate Hymenoptera (Apidae, Halictidae) ( sp.) and beetles in the genus () (Linsley et al. 1952; Svácha 1994; Falin 2002). Campbell (1991) reported 10 species of Ripiphoridae from Canada but none from the Maritime provinces. Majka et al. (2006) reported (Say) for the first time for New Brunswick and Nova Scotia and the Maritime provinces. William McIntosh (former director of the New Brunswick Museum) in an unpublished manuscript reported a specimen of (LeConte) (determined by W. H. Harrington) from Saint John, collected sometime between 1898 and 1907 (Majka et al. 2006). To date, no specimen has been found to support this record and this record is considered questionable. Here, we report another species of Ripiphoridae for New Brunswick and the Maritime provinces.

Methods and conventions

The following records are based on specimens collected during a general survey by the first author to document the Coleoptera fauna of New Brunswick and from by-catch samples obtained during a study to develop a general attractant for the detection of invasive species of Cerambycidae. Additional records were obtained from specimens contained in the collection belonging to Natural Resources Canada, Canadian Forest Service - Atlantic Forestry Centre, Fredericton, New Brunswick.

Collection methods

Many specimens of Mordellidae were collected by sweeping vegetation or flowers. Others were collected from Lindgren 12-funnel trap samples during a study to develop a general attractant for the detection of invasive species of Cerambycidae. These traps visually mimic tree trunks and are often effective for sampling species of Coleoptera that live in microhabitats associated with standing trees (Lindgren 1983). See Webster et al. (in press) for details of the methods used for trap deployment and sample collection. A description of the habitat was recorded for all specimens collected during this survey. Locality and habitat data are presented exactly as on labels for each record. This information, as well as additional collecting notes, is summarized and discussed in the collection and habitat data section for each species.

Distribution

Distribution maps, created using ArcMap and ArcGIS, are presented for each species in New Brunswick. Every species is cited with current distribution in Canada and Alaska, using abbreviations for the state, provinces, and territories. New records for New Brunswick are indicated in bold under Distribution in Canada and Alaska. The following abbreviations are used in the text:
